- LUBRIoA'roR.

1 To all whom it may concern 7 I 1 Be it known that I, LAUDIE J MRUK,

citizen of the United States, residing at Butte, in the county ofSilverbow and State of Montana have invented certain new and useful Improvements in Lubricators, of

i which the following is a specification.

This invention relates to lubricators specially adapted for use in connection with the carsused in mines andother similar places; and it consists 1n the'novel construction and combination of the parts hereinafter fully I; described and claimed. A lubricator of this I sort is preferably made to hold a considerable supply of hot tallow and-of lubricating oil which are kept separate from eachother and which are used on different parts of the same" car; but it may also befilled with one kind of oil; orfit may be filled with any two lubricants of different density or fluidity. In" lubricating mine cars it is desirable to have both sorts of lubricant on hand, and in chambers which are connected i together in a single device or structure,

and tohave a liberal supply of each lubricant, sothat a numberof cars can be lu'bri cated without having to refill the lubricator.

."*-In the drawings, Figure 1 is avertical sectionthrough a lubricator constructed according to this invention. Fig. 2 is a crossseetion-,"taken on theline mw in Fig. 1.

The shell 2 of the lubricator is preferably a cylinder formed of sheet metal or other suitable material, and it is provided with a v bottom 3 at its lower end. A" removable cover 4 is secured to the top end of the cyl inder. "The cylinder has three partition plates or false-bottoms 5, 6, and 7. The

upper partition 5 forms the bottom of the grease chamber 8, which is in the upper part of the shell. The middle partition 6 forms the top of the oil chamber 9; and a i heating chamber 10 is formed-between the two chambers 8 and 9. The partition 7 forms the bottom of the oil chamber 9, and another heating chamber 12 is formed between the partition 7 and the bottom 3.

.1 The bottom of the heating chamber 10 is provided with candle sockets 14, and the bottom of the heating chamber 12- is provided with candle sockets 15-. Candles 16 are placed in the candle sockets, and are provided to heat the lubricant in the 0113,111

bers above them. Four candles are preferably arran ed in each heating chamber, but other simi ar heating devices may be used,

and they may be supported in any approved way; -Door openings 18 and 19 are provided in the respective heating chambers 10f and 12, and are formed in the side wall of the These' openings are provided with guides 2-2 and 23 on the shell. Any other approved form of door may be used which will permit the candles being placed in posi tion, and the door may beleftslightly open to support combustion, or any suitable air holes may be provided. Each heating chamber may also have a plurality of slidable doors and door openings if desired.

.A' stay 25 is arranged centrally in the lubricator shell, and is securedto the bot- 7 tom 3 and to the three partitions 5, 6, and 7.. This stay strengthens thepartitionsand also compensates the shell for the loss of material cut away to form the door openings of the heating chambers. The partitions 5, 6, and 7, are also reinforced, thickened orbraced in any approved way where .the stay is secured to them. The lower part'2l6 of the stay may be a solid rod of metal, an'dlits upper part 29. is preferably tubular and is provided with a T junction pipe27 having anoil outlet 28 on one side which discharges into the oil chamber 9. The tubular upper part 29 of the stay ex- A plug 30 is provided for closing the upper end of the tube or pipe 29. .Whenthis plug is removed it may be screwed into a socket on thetop partition plate to'hold it stationary and prevent its loss.

The oil chamber 9 is provided with an oil inlet or charging hole 32 having a suitable cap, and it has an oil outlet branch or pipe 33 to which any suitable flexible oil pipe and tends throughthe upper heating chamber.

regulating valve are attached. A check valve 34 is also provided, and compressed air is forced into the upper part of this chamber 9 from time to time so as to expel the oil.

The upper chamber 8 is filled with tallow or other normally stiff grease by removing the cover, or in any other convenient way.

The upper chamber is also provided with an outlet branch or pipe 35 for the connection of a flexible pipe or other attachments, and

it has a check valve 36 to admit compressedair to expel its contents when it is used for oil.

The thick grease is preferably expelled from the chamber 8 by means of a piston 38; p

ing the push-rod. The piston is prevented from revolving by itsfrictional contact with the wall of the chamber, but any. suitable guide may be provided if desirable.

When stiflz' grease is not required",and, a

large supply of oil isdesirable, theplug 30 is removed, and oil is poured into the upper chamber untilboth chambers are filled, The

candles of the two heating chambers'heat the oil, and prevent it'from freezing when the-temperature isvery-low. When a lubricator of this construction'is used, a large number of cars can be lubricated without having to refill the device. As each car is lubricated by the one device there is less danger'of parts of a car being overlooked, or of cars being overlooked altogether, which 'is apt to be the case when small separatelubricators are used for grease and for oil. By having a singleshell provided with chambers for grease .and' oilsarranged one above the other, and having two supply of lubricant can be carried about from carto car and kept incondition for use.
